Effects of Deceleration on Secondary Collisions between Adult Occupants and the Vehicle in Frontal Crash Accidents

In developing countries like India, Multilane high-speed National Highways (NHs) are victims of high accident rates. The Indian National Highway network comprises only 2% of the Indian road network, but transports 40% of traffic, resulting in traffic accidents on National Highways. As observed from past studies, drivers are the main responsible factors for accident causation due to their risky behavior. Hence, to determine significant factors causing the risky behavior of drivers on multi-lane high-speed highways, the personal interview survey through questionnaire was conducted for the road users of NH-47 comprising of the responses to the drivers' demographics, attitude towards vehicle condition and maintenance, traffic regulations/ enforcement following attitude characteristics, and roadway environment characteristics. Principal component analysis (PCA) was applied to the questionnaire variables, and significant category-wise variables for risky driving were identified. Fifteen important variables contributed to risky driving behavior from the questionnaire database by PCA. They are Roadway environment characteristics like improper signals, roadside accident prevention infrastructure, improper pavement, and no safe crossing points; Driver's age and experience; Using mirrors while overtaking, using lights and dipper during night-time, and using hand signals during daytime; Using helmets and seatbelts while driving and having a valid vehicle insurance policy; age of the vehicles, vehicle service frequency, and lane preference in their decreasing significance based on the questionnaire database. The authorities can take suitable measures to control the significant variables causing risky driving behavior on high speed multi-lane highways and reduce the accidents scenarios on the multilane highways.

“…Being an effective way to simulate and reproduce real crash accidents, dynamic tests were conducted in a devised pattern to verify the effect [32,33,34]. In most regulations and technical standards, the resultant chest acceleration shall not exceed 55 g except during periods whose sum does not exceed 3 ms, and the vertical component of the acceleration from the abdomen towards the head shall not exceed 30 g except during periods whose sum does not exceed 3 ms.…”

Infant carriers play an important role in protecting child occupants from severe injuries caused by collisions, but the tension of harness webbing cannot be controlled properly most of the time. Infant carrier’s user manual or instruction generally contains little information about the extent to which the adjusting belt should be pulled to cause the necessary webbing tension, and it is often neglected that the infants should be restrained securely. In order to improve public awareness, it is important to ascertain the effect of infant carrier’s webbing tension on the occupant’s chest accelerations. A testing scheme including 12 dynamic tests was devised and conducted, and test conditions were controlled strictly to ensure the accuracy and objectivity of results. P1.5 dummy’s resultant and vertical chest accelerations were collected and analyzed. Both ISOFIX installation and seat belt installation methods were taken into consideration without lack of generality. Sled’s accelerations and velocities were set and acquired, which constituted the fundamental testing conditions of dynamic tests and ensured the repeatability and reliability of tests. Furthermore, dummy’s chest acceleration pulses were monitored and recorded, and the data were evaluated in accordance with criteria defined in relevant technical standards. The dummy’s chest accelerations were classified into 2 groups according to child restraint systems’ installation methods, i.e., the ISOFIX group and the seat belt group. In each group, both resultant chest acceleration and vertical chest acceleration were involved. Universal phenomena were displayed in all the tests, and the larger the tensile forces were, the lower the chest accelerations were in tests. Based on experimental validations, the relation between webbing’s tensions and chest accelerations in frontal crash accidents was verified. Furthermore, suggestions were made about adjusting the webbing tension and the proper use of infant carriers.
